Title: Latent images on coins
Post by: <k> on January 19, 2013, 09:24:38 PM
Latent images are used in order to make a coin harder to forge. If you tilt the coin to a certain position in the light, you will see the latent image.

Many Luxembourg €2 commemorative coins show latent image. Here's one for example..

I previously thought Japan's "new" 500 yen was the first to break into this field, but clearly not.

As far as I remember, the Spanish Mint (FNMT-RCM) was the first one to use latent images on circulation coins. Was about 20 years ago; will have to check a catalog ... más tarde. :)

Japanese 500 Yen coins from 'Prefectures' series show latent image on obverse. Attached a small scan, however latent image is not visible. The central square displays '60' when the coin is hold at an angle. :) (60 stands for 60th Anniversary of Enforcement of the Local Autonomy Law)

Ah no - it was precisely 20 years ago. :)  In 1987 Spain issued a new 500 pesetas coin; it shows King Juan Carlos and Queen Sofía (depicting both made sense also because '87 was the year of their 25th wedding anniversary). In 1993 a modified version was issued, with a latent image on the reverse. The coins were used as regular circulation coins until the introduction of the euro cash. The first attached image shows both sides of the coin - a large image of a '93 piece is here (http://upload.wikimedia.org/wikipedia/commons/1/16/1993_500_Pesetas.jpg) for example. The latent image shows either the last two digits of the year of issue (in the second attached image that is a "96"), or the crowned "M" mintmark of the Madrid mint.

Spain €20 (2010), shows latent image of FNMT's mint mark / 10 depending on angle in which it is held.

Yeah, those latent images are hard to photograph, so a design study will actually show the details better. :)  Strictly speaking, what we have seen in this topic are different technologies. When the first latent images were used, they would show two views. The Dutch "geboortemunt" (2004) had three different angles; the Dutch Mint called that MultiView Minting. And the Luxembourgish coin in reply #4 uses what the KNM calls Minted Photo Image ...

In fact we already mentioned about some other similar coin who had a quadruple latent image, that is Spain 2012, 30 euros.

I mentioned that I attended the FNMT speech in WMF Media Forum. In NumismaticaVisual's Spanish blog they uploaded the video about this coin. You can see the quadruple latent image in minute 2:30 and 3:30.
Unfortunately, the video is in English.  ;D ;D ;D
http://jeroja6.wordpress.com/2012/02/10/espana-video-presentacion-programa-numismatico-wmf-2012/

Thanks for that, I just watched the video. Oh, and I noticed that the same YouTube user posted a few more Media Forum videos! http://www.youtube.com/user/vicepresidentADE?feature=watch

What I don't quite understand is ... the man who presents the program talks about this unique feature - but when the Dutch mint made its Muntgebouw coin last year, the designer Juanjo Sanchez (yet another guy from Spain talking in English :) ) mentioned how much time it had taken him to develop this six-"sided" latent image:

(interview) http://www.youtube.com/watch?feature=player_detailpage&v=CCpwehEL6BE#t=164s
(here he shows the image) http://www.youtube.com/watch?v=g_zhX3b9qMI

So what I think is new about this coin is not so much the fact that a latent image can show more than two "elements". This one is special in that the four latent images always show four different elements, which is probably not that easy to achieve ...

The latent images of two Chinese phrases, "the country is prosperous and at peace" and "the people live in safety and happiness", overlap to form the shape of a Ruyi. The face value 10 Yuan in Chinese is inscribed with two latent images inside the Arabic numeral "0", one of which shows the map of Taiwan.

You can read 2 different words and see 2 objects(Flower and map) if you see this coin in different angle!

The Dutch "geboortemunt" (2004) had three different angles; the Dutch Mint called that MultiView Minting.

Here is how KNM explains its gimmick. Grandma is on one side, seen here twice. The other side shows three portraits: parents and baby.

And while it is not quite there yet ;) we could already add the new £1 coin from the UK. A latent image that shows either the digit "1" or the pound sign.
